hi all, here's the result of my work on the machine so far, the idea was to generate a note using the audio input:
- first you hear a (very) short snippet of music (tortoise - standards)
- then you hear the dsp generating two notes (first an A than a G) using the acquired samples

A few results are presented in sequence... thanks for listening !

It's an interesting sound you've got there. Unfortunately I don't understand fully what's going on except that a sound is captured and then transformed and played back in some way. I'd love to hear more about what the process is.

You got it right, first the data coming for the audio in is stored in memory (and played back), then, when the 'buffer' is full, the acquired data is used to produce the A/G notes (the two long sounds that you hear after the short piece of music).
To generate the notes, the sampled data is 'sliced' into short sequences (whose lenght determines the note frequency) and each 'slice' is reproduced a given number of times; after that the next 'slice' is reproduced, and so on... until all the data in the buffer has been used.

Another update, I added a midi control for portamento and to define the numbers of iterations for each 'slice'.
Also, I implemented an 'audio in monitor' function, so that it's possible to monitor the audio in, and decide when to 'sample'.
Short audio file attached.
